Perfecta Bravό take-home whitening treatment contains a patented, water-based formulation that hydrates teeth as they whiten to avoid sensitivity. The 9% hydrogen peroxide treatment has a wear-time of 30 minutes, once per day. It provides significantly less wear time without sensitivity. It is said to increase patient compliance and offer patients an improved professional tooth-whitening experience in comparison to both OTC and other at-home products. The results are lasting—at least 2 to 3 years for most patients. For more information, call (888) 670-6100 or visit www.premusa.com.
